Organic light-emitting device

An organic light-emitting device includes electrodes and light-emitting units each including an emission layer; and a charge generation layer, including n- and p-type charge generation layers, disposed between each adjacent pair of light-emitting units. A wavelength of maximum intensity of light emitted from one of the light-emitting units may be different from another, an n-type charge generationlayer may have a metal-containing material having a work function of about 2.0 eV to about 4.5 eV, and a p-type charge generation layer may be formed of a hole transport material, an absolute value of a HOMO energy level of the hole transport material being greater than about 5.5 eV, and an absolute value of a LUMO energy level of the hole transport material being less than that of a LUMO energylevel of a hole transport layer of a light-emitting unit adjacent to the p-type charge generation layer. 有机发光装置包括：电极和各自包括发光层的发光单元；以及电荷产生层，所述电荷产生层包括n型电荷产生层和p型电荷产生层，置于每对邻近的发光单元之间。由发光单元中的个发光单元发出的光的最大强度的波长可以不同于由发光单元中的另个发光单元发出的光的最大
